急性心肌梗死早期开通血管有利于挽救濒死的心肌、保持乃至提高左室的功能;择期再通闭塞的梗死相关血管可提高左室收缩功能和改善左室重构,其原因在于再灌注可挽救潜在存活的或者冬眠的心肌,恢复前向血流对梗死周围心肌仍有益,并且减轻左室重构、降低心室不稳定性从而减少心律失常发生和为其他区域提高侧支循环;其机制还需要进一步研究。
In the early stage of acute myocardial infarction, the opening of the blood vessel is conducive to saving the dying myocardium and maintaining or even improving the function of the left ventricle. Elective recanalization of occluded infarct-related blood vessels can improve left ventricular systolic function and improve left ventricular remodeling due to reperfusion Potentially surviving or hibernating myocardium, restoration of antegrade blood flow is still beneficial to the myocardium around the infarct, relieves left ventricular remodeling, decreases ventricular instability, reduces arrhythmia and improves collateral circulation in other areas; its mechanism also requires further research.
